The seat plate 10 for the chair 100 according to an embodiment of the present invention includes a base member 1, a cushion member 2, and a cover member 3.

Here, the bottom plate member (1) forms a basic base on which each component is combined, and the cushion member (2) is placed on the bottom plate member (1) and then finished with the cover member (3).

The bottom plate member (1) includes a connecting surface (11), a bottom surface (12), and a side surface (13). The bottom surface (12) is formed as a horizontal surface and a coupling hole (121) for fixing the armrest (5). ) is formed. In addition, a pair of side surfaces 13 is formed by protruding from both sides of the bottom 12 so that the ends are inclined, and a coupling hole 131 for fixing the armrest 5 is formed.

Accordingly, the armrest formed by bending can be fixed to the bottom and side of the bottom plate member, respectively, so that the armrest can be firmly coupled.

Meanwhile, the connection surface 11 connects the ends of each pair of side surfaces 13. Since the side surface 13 is made of an inclined surface, the first connection surface 111 on one side has a low height, and the second connection surface 112 on the opposite side has a high height. The cushion member 2 is coupled to the side surface 12 and the connection surface 11 and is placed in contact with the bottom surface 12 of the bottom plate member 1. At this time, the cushion member 2 is covered with the cover member 3 to protect the cushion member 2.

With this configuration, if the seat plate is formed by placing the low-height first connection surface toward the legs, it is possible to provide more cushioning to the user's thighs and greatly reduce the interruption of blood circulation due to the thighs being pressed.

Hereinafter, the configuration of each part will be described in detail with reference to the drawings.

Figure 1 is a perspective view showing a seat plate according to an embodiment of the present invention, and Figure 2 is an exploded perspective view showing this seat plate.

The bottom plate member (1) serves as a basic base to which each component of the seat plate (10) is combined and includes a connection surface (11), a bottom surface (12), and a side surface (13).

The connection surface 11 of the bottom plate member 1 has different heights at the front and rear as described above. Referring to the drawing, the connection surface 11 is configured to be lower at the front where the user's legs are placed and higher at the back where the buttocks are placed when the user sits.

The side surfaces 13 are formed to protrude from both sides of the bottom surface 12. The side (13) is coupled to the cushion member (2) to ensure that the cushion member (2) is properly positioned. Meanwhile, a coupling hole 131 is formed on the side 13 for fixing the armrest 5.

Referring to the drawing, the armrest 5 has a bent shape and includes a horizontal surface 51, a vertical surface 52, and a handle 53. At this time, the horizontal surface 51 is in close contact with the bottom 12 of the base member 1, and the vertical surface 52 is in close contact with the side 13. The horizontal surface 51 of the armrest 5 has the bottom 12. A hole is formed at a position corresponding to the coupling hole 121, and a hole is formed on the vertical surface 52 at a position corresponding to the coupling hole 131 of the side 13, and the armrest (5) is formed by a binding member penetrating each hole. ) has a form that is coupled to the bottom plate member (1).

In particular, the coupling hole 131 formed on the side 13 fixes the armrest 5 in a different direction from the coupling hole 121 formed on the bottom 12, so that the armrest 5 is firmly attached to the base plate member 1. so that they can be combined.

Meanwhile, the coupling hole 131 formed on the side surface 13 can be formed after appropriately modifying the shape of the side surface 13. As an example, the drawing shows a form in which a coupling body for forming a coupling hole 131 is formed in the lower part of the side surface 13 and a coupling hole 131 is formed in the coupling body.

Alternatively, a coupling hole may be formed in the lower part of the side 13 without a coupling member, the vertical surface 52 of the armrest 5 may be modified to come into close contact with the lower part of the side 13, and then coupled with a binding member.

Additionally, a chin 132 may be formed on the upper end of the side 13 of the bottom plate member 1. Accordingly, the fitting groove 21 of the cushion member 2, which will be described later, may be bent in an 'L' shape to correspond to the chin 132. In this state, the side surface 13 is coupled to the fitting groove 21 so that the cushion member 2 can be coupled to the bottom plate member 1. Such jaws may also be formed on the connection surface 11.

The bottom 12 forms the lower part of the bottom plate member 1 and the leg member 30 is coupled thereto. A coupling hole 121 for fixing the armrest 5 is formed on the bottom 12. It is desirable to form a plurality of coupling holes 121 on the bottom surface 12.

A protrusion 111 may be formed on the bottom 12 of the bottom plate member 1 to prevent the cushion member 2 from slipping. The protrusions 111 are preferably formed long in the width direction. These protrusions 111 allow the cushion member 2 to be positioned more stably.

Meanwhile, a friction member having roughness may be provided on the bottom surface 11 instead of forming the protrusion 111 or together with the protrusion 111.

Additionally, ribs 124 may be formed on the bottom surface 12 with a lower height toward the center of the bottom surface 11. Specifically, as shown in the drawing, the rib 124 in the shape of a right triangle with an inclined surface may be configured to contact the bottom 12 and the side 13. At this time, the inclination of the ribs 124 may be around 60 degrees. Accordingly, when the user sits on the seat 10, the buttocks are brought together to the center, thereby providing a sense of stability.

Meanwhile, a protrusion 122 with a hole formed in the center may be formed on the bottom 12 so that the support 62 of the footrest 6 can be inserted and moved, and the support 62 may be formed by extending from the hole of the protrusion 122. A guide groove 123 may be formed to guide the movement of .

Figure 3 is a plan view showing the bottom of the bottom plate member employed in the embodiment of the present invention. Referring to the drawing, the chair 100 may be provided with a footrest 6 consisting of a cushion 61 and a support 62. In order for the support 62 of the footrest 6 to be coupled to the seat plate 10, the above-described protrusion 122 may be provided on the bottom 12 of the bottom plate member 1.

At this time, the protrusion 122 has an approximately semicircular shape, and a circular hole is formed across the bottom surface 12 and the protrusion 122, similar to the cross-sectional shape of the support 62. Meanwhile, behind the protrusion 122 on the bottom surface 12, a guide groove 123 is formed extending from this hole and having a roughly semicircular cross-section.

Accordingly, the support 62 of the footrest 6 can move along the hole and the guide groove 123, and the footrest 6 can be in close contact with the seat plate 10 or positioned away from the seat plate 10. Additionally, the footrest (6) can be directly coupled to the seat plate (10) without using separate parts.

This bottom plate member 1 can be molded at once as an injection molded product in which the connection surface 11, the side surface 13, and the bottom surface 12 are continuously integrated.

The cushion member 2 is placed on the bottom 12 of the bottom plate member 1 to provide a cushioning feeling when the user sits. Referring to the drawing, the cushion member (2) is placed on the bottom surface (12) of the bottom plate member (1) with one surface coupled to the connection surface (11) and side surface (13) of the bottom plate member (1).

At this time, the cushion member (2) is coupled to the bottom plate member (1) with the low first connection surface (111) at the front and the high second connection surface (112) at the rear, so that when the user sits, the cushion member (2) is coupled to the bottom plate member (1). The part is located on the lower side of the connection surface. Accordingly, the force pressing the thigh area is reduced, preventing blood flow disorders in the legs and improving seating comfort.

In addition, a fitting groove 21 is formed in the cushion member 2, and the connecting surface 11 and the side 13 of the bottom plate member 1 are coupled to this fitting groove 21, so that the cushion member 2 is a bottom plate member ( It can be placed on the underside (12) of 1). Accordingly, the cushion member (2) can be stably coupled to the bottom plate member (1).

At this time, when the ledge 132 is formed at the upper end of the connection surface 11 and the side 13, the fitting groove 21 of the cushion member 2 may also be formed as a groove having a shape corresponding to the ledge 132. In this case, the bottom plate member (1) and the cushion member (2) can be more firmly coupled.

The cushion member 2 may be made of a material that is easily deformable and has a cushioning feel, such as memory foam sponge, which is generally used for the cushion 61 of the chair 100.

The cover member 3 is a component that functions to cover and protect the cushion member 2. Referring to the drawing, the cover member 3 has a rectangular shape to correspond to the cushion member 2.

At this time, the edge 31 of the cover member 3 is sewn and a tightening string 32 is provided in the space formed along the edge 31. Accordingly, after the cover member 3 covers the cushion member 2, the cover member 3 can be coupled to the cushion member 2 to prevent it from being separated by tightening the drawstring 32.

Meanwhile, a fixing member 4 such as a tacker needle can be fixed to the side 13 of the bottom plate member 1 by penetrating the cushion member 2 from the sewn edge 31 of the cover member 3.

The cover member 3 may be made of a material generally used in the seat panel 10 of a chair, such as mesh net, leather, or cloth.
